The Diesel Particulate Filters (DPFs) are a mandatory retrofit device
that is required for Heavy Duty Diesel Fueled engines. DPFs are high
maintenance and expensive retrofit devices that CARB is requiring for
all Heavy Duty Diesel Fueled Engines.

The cost for the retrofit is estimated to be approximately $10,000 for
the device itself. The cost of maintenance appeard high for
this high maintenance device. Part of the enforcement will
apparently be a check to see that the device has been maintained in
accordance with guidelines issued by CARB.

This device will
cause a substantial increase in the costs for all operators of devices
with Heavy Duty Diesel Fueled engines. The added costs will probably
force many small operators out of business.

According to estimates by The State of California, approximately half
of the Trucks operated in The State of California are operated by the
owners of small Trucking Companies.

The small Trucking companies are least able financially to handle the
added costs and many will be forced out of business.

In addition there
is another mandatory retrofit device called a Selective Catalytic
Reduction System (SCR). Estimated cost of that device is also
approximately $10,000.

The SCR is also a high maintenance device.

The SCR operates by injecting a solution of UREA into the Deisel Engine
as it operates.

The Urea breaks down in the engine to release Ammonia. In theory the
Ammonia reacts with Nitrogen Oxides produced by the engine, reducing
the Nitrogen Oxides to Nitrogen.

In the process
more particulate matter is created which is supposed to be filtered out
of the exhaust by the DPF.

The result of the new
CARB Regulations will be a large number of small operators forced out
of business because of the dramaticlly increased costs of operation.

That will result in a
severe truck shortage in the near future for the transportation in
goods and services in The State of California.

Transportaion of
highly perishable products such as fresh fruit and vegatables
will be severly limited. This will have a severe negative impact on the
farming industry in The State of California.

Many farms will not
be able to get highly perishable fruit and vegatables to market in a
timely manner.

This will result in
the spoilage of large amounts of fruit and vegetables and large
monetary losses to farms in The State of California.

The likely result is
that many small family farms will also be forced out of business as a
result of the financial losses.
